Specification of Letters Patent. Patented June 1l, 1915.

Application led February 12, 1914. iSerial No. 818,427.

' T0 all 'whom it may concern f Be it known that I, ULRICH REIDT, a subLject of the Emperor of Germany, residing at Los Angeles, in the countyof Los Angeles and State of California, have invented/certain .new anduseful Improvements in Permutation-Iadlocks; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to new and useful improvements in permutation padlocks and resides. in the provision of a lock which is simple, reliableand eflioient and cheap to manufacture.

An important object of my invention is i to provide a lock of thecharacter described which employs -a novel form of locking means whichis simple as to construction, reliable and expeditiousin operation andwhich'may be cheaply manufactured.

The above and additional objects are accomplished by such means as areillustrated inthe accompanying drawings, described in the followingspecification and then more, particularly pointed out in the claimswhich are appended hereto and forma part of this application. Withreference to the drawings, wherein I have illustrated the preferredvembodiment of my invention as it is reduced to practice, and throughoutthe several viewsof which similar reference numerals designatecorresponding parts: Figure l is a view in elevation of the lock showingone of the sides of the lock casing removed, Fig. 2 is a sectional viewtaken on line2-2 of Fig. 1, Fig. 3 is a top plan view, Fig. 4 is afragmentary detail sectional view. of a portion lof the looking meansyforming a part of the invention.- Fig. 5 is a` fragmentary sideelevation with the plate removed partly in section.

Referring to the drawing the numeral 1 designates as an entirety a'lockcasing in which is mounted a. sliding shackle 2. This casing 1 isprovided with the usual removable side wall 3 that is secured by boltsor other suitable fastening means. One end of the shackle 2 is longerthan the other and has rotatably mounted thereon a cylindrical sleeve 4which is provided at its ends with annular flanges 5 and 6. The longerend of the shackle 2 is reduced to provide a shoulder 7 that is disposedadjacent the free end of the shackle. The sleeve 4 is reduced at itslower endv to provide a shoulder 8 arranged'to coperate with theshoulder 7 to prevent upward movement of the sleeve upon the shackle 2.The extreme end of the shackle may be enlarged to prevent downwardmovement of the sleeve 4. An outwardly extending annularflange 9 isformed on the sleeve 4 adjacent but spaced from the lower end thereof.This flange 9 is provided with a recess 10 which terminates inwardly atthe curved face of the sleeve, and is for a purpose to be laterdescribed. An opening 12 is formed in the sleeve 4 and is adapted forregistration with a recess or indentation 13 that is formed in theshackle 2 in that part which is incased within the sleeve 4. The flange6 on the lower end of the sleeve 4 rests in engagement with a flange orshelf 14carried by the casing as will be clearlv seen with reference toFig. 1 in the drawings.

Mounted centrally ofthe lock casing 1 adjacent the upper portion thereofis a pair of arcuate plates 15 and 16 that are pivoted centrally oftheir ends as at 17. Pivoted between the plates 15 and 16 at the. innerend thereof is a bolt 18 v.that is slidable through a suitable guide 19and arranged t0 extend through the opening 12 in sleeve 4 into therecess or indentation 13 of the shackle2. rIvhusit is seen that one endof the shackle 2 is adapted to be locked against removal from thecasing 1. Iivoted between the plates 15 and 16 adjacent the other endsthereof isa bolt 20 that is slidable through a suitable guide 21 andarranged to fit within a recess or indentation 22 formed in the]adjacent end of the shackle 2. As a means for holding these plates 15and 16 1n such a position that theA bolts 18 and 20 arenormally inextended or locked position there has been provided a leaf spring 23that 1s secured in any suitable manner at one end as at 24,'passesthrough a suitable guide 25 and engages at its free end one face of theplates 15 and 16 thus holding the bolts18 and 20 in extended position.

Assuming that the shackle 2 is locked at both ends as illustrated inFig. 1, to unlock Aloo the shackle the sleeve 4 is so turned that the lopening 12 therein is moved away from the bolt 18. In this connection itwill be noted that the bolt 18 is beveled upon its side faces and top sothat a reduced end is provided. Upon engagement of the edge of theopening 12 in the sleeve with the adjacent beveled face of the bolt 18,which face` acts as a cam,'thelbolt will be moved outwardly lrelative'to the opening 13 in the shackle and cause the bolt to be movedout of locking engagement. Rotation of the sleeve is continued until therecess 10 in the flange 9 isl in alinernent with the end of the boltwhen the shackle 2 isfree to be moved outwardly from the `casing 1 sinceat the time of the vmoving ofthe opening 12 in the sleeve4.- from thebolt 18 the inwardmovement imparted the bolt is suiiicient to withdrawthe bolt 20 from engagement with thegshackle 2.

. Thus the shorter end of thelshackle may be lwithdrawn from the lockcasing 1 and the unlocking is provided. The bolt 18 engages the flange 6and prevents withdrawal completely of the shackle 2. It is found prefJerable to form the indentations 13 and 22 in sary to`impart a series ofturns to the sleevel the nature of notches thus permitting a snugfitting and -proper release.

It will be readily observed with reference to the foregoing 'descriptionand accompanying drawings thatv Iphave provided a slmple and eilicientform of lockwhich may be before the desired locking or unlocking actionis provided.

In reduction to practice, I have found that the form of my invention,illustrated in the drawings and referred to in the above description, asthe 'preferred embodiment, is the most eiicient and practical; yetrealizing that the conditions concurrent with the adoption of my devicewill necessarily vary,

I desire to emphasize the fact that various 1 45 minor changes indetails of construction, proportion and arrangement of parts may beresorted to, when required, without sacri- -ficing any of the advantagesof my invention, as defined in the appended claims.

-What is claimed is z- 1. A lock comprising a casing, a shackle slidabletherein, a sleeve rotatably journaled upon one terminal of, saidrshackle and diseach end, said 'sleeve having an opening therein arrangedto communicate with the notch in the adjacent end of said shackle, anannular flange formed on' said sleeve adjacent to the openingtherein andbeing pro vided with a recess, an annular iange formed on the eXtremeinner end of said sleeve, bolts pivoted within the casing and adapted`for registration with the notches in said shackle, one of said bolts\being arranged to bear upon the upper face of the iange that is arrangedadjacent to the opening in said ,sleeve when said sleeve is rotated andspring means for normally holding 'said bolts in extended position.

2. A lock comprising a casing, a shackle slidable in said casing, asleeve rotatably journaled upon, said shackle and disposed partly withinsaid casing and having Ian opening therein intermediate its ends, anannular ange thereon adjacent to the opening, a recess therein, anannular flange on the lower end of said sleeve, a bolt pivoted withinsaid casing and arranged to extend through said opening,.said shacklehaving "a notch therein disposed for alinement with said opening, saidbolt arranged to fit within the notch and disposed at its free endnormally above said rs't .named ange and means for normally holding saidbolt in extended osition.

3. A ock comprising a casing, a shaekle slidable in. said casing andhaving notches adjacent each end,a sleeve mounted upon said shackle anddisposed partly within said casing, a-pair of bolts slidable andpivotally mounted within said casing andarranged to coperate with saidnotches, said sleeve having an openingtherein to receive `011e of thebolts, said opening arranged to aline with one of the notches in'saidshackle whereby the bolt may engage said last named notch,

and means for normally yieldinglyyholding said bolts in extendedposition.

In testimony whereof I affix my signature in presence of two witnesses.v
